Nashua 357 Premium Grade Duct Tape is the duct tape professional contractors choose when they require a consistent, trouble-free product. It has a high tensile strength and is very durable. Its clean release resists delamination and it conforms to a wide variety of surfaces. It also tears straight, resists curling, and has outstanding performance over a wide temperature range. Nashua 357 uses include HVAC (heating, ventilating, air conditioning) and refrigeration applications. Also asbestos removal applications, sealing of seams and joints in metal air handling systems, sand and media blasting applications, and the manufacture of flexible duct equipped with metal collars. It is a great tape for bonding, protecting, holding, repairing, patching, packaging, bundling and motor sports. Also please note that Nashua 357 comes to our converter in log roll format (that is why the tape can be offered in non-standard widths) and because of that rolls will more often than not ship on plain white cores. This tape was recently featured in the MythBusters’ ‘Duct Tape Hour’ episode.
